W'arrem'iin the county oflVarrenan d State of Pennsylvania, have invented 'new "and useful Improvements in Coupling Members for Hame-Fastenings, of which the following is a specification.

This invent-ion relates to improvements in hands fastenings and it has more particular reference to a device which forms an element of the complete hame fastening and is designed to associate the latter with relative permanency to one of the hames. say, the com lete hame fastening has at one end a suita ly constructed-ccatch' which is manipulated to connect or disconnect thehames whenever the-latter are to be applied .t0 or removed from the collar, and at its other end, a device which embodies the present improvement, and which, while detachably associated with the other hame, is not intended to be disconnected therefrom each time that the hames are removed from the collar.

The object of the invention is to provide a device of the character referred to which is of unitary nature, and which may be associated in a safe and positivemanner, both with the hafne to which it is to be connected,

and With the chain or equivalent part of the hame fastening, and which may be quickly and'easily connected and disconnected from both of-the elements referred to and secured at any desired point-on the chain to enable "the length of the latter to be increased or decreased as circumstances may require a fastening of greater or less length.

An embodiment of the invention is illustrated in the accompanying drawing, whereinFigure 1 is an elevation of a hame fasl tening including a device which embodies the present improvement; Fig. 2 is a top plan view of the saiddevicey-Fig. 3 IS a sectional view thereof, the parts being locked or normal position; Fig. i is a sectional view, the parts being in unlocked p'os1- tion.

Similar characters of reference designate corresponding parts throughout the several views.

The hame fastening shown in the drawin by way of example includes a safety hook of suitable construction, a chain B which is. connected at one end of the safety hook, and an attachment device C,-which forms the That is to;

if subject of the present invention. The at- -tion of the part1 with the elements which are engaged bythe hooks 2 and 3 may be of employed. The pin 4, includes a shank 4; and afinger 4 which project-s at-a right angle from the upper end of the shank and :has' an int'urned extremity. The shank 4* passes loosely through an opening 5 in the shank of the body 1, the end walls of the opening 5 being parallel and inclined, whereby said opening has, in longitudinal section, the outline of a ,rhomboid. The inturned extremity of the finger 4* is, in the normal relation of the parts, engaged in a recess 6, formed in the upper side of the hook 2, and it serves the purpose of positively holding the locking pin 4 in operative relation.

site to the finger 4 with a head 4, which serves as aseat for an expansive 'coil spring '7. The spring 7 is confined in a sleeve 8. an'd'its one end bears as above stated against- Ythe head4-. whileits other end bears against a flange 9 atthe upper end of the sleeve 8. The spring 7 cciacts with the inturned extremity of the finger 4 in maintaining the operative relation oi? the locking pin,s erving the pin as-will prevent the accidental disengagement of the int-urned end of the finger 4* from" the recess 6, as is obvious.

In the operative relation of the device, the

the hooks 2 and 3, the upper portion of the pin closing the book 2 and thus preventing the latter from becoming disconnected from the ha me ring, and the lower portion of the pin, which is surrounded by the sleeve 8 closing the hook 3 and in like manner preventing the latter from becoming disconnected from the link of the chain B.

In case it is necessary or desirable to'disconnect the device 0 from the hame or from the chain, or from both, or to increase or de-' gaging-the book 3 with any particular link,

of the chain B. In order that the associasafe and positive nature, a locking pin 4 is this purpose by putting such a tension on locking pin serves as a closure for "both of,

crease the efiicient length of the chain by enpecifi i ten men Patented Nov.26,1912.

The shank 4 is formed at the end oppo- Y efi'ect, universally movable, within certain be dissociated, to be made quic y and with facility. Fig. 4 shows the pin in suchposition that/both of the hooks 2 and3-are open .central opening theend walls'of which are both from the hame ring and from the link ing an ogee body part having its ends the operation can'be very readily carried out I by pulling the pin 4 upwardly against the tension of the s ring 7,'so as to disengage the 'end' of the nger 4: from the recess .6, and then by moving said pin in such a tlirectionas may be necessary. The pin 4 is, in

limits, and it may be turned also on the axis of its shank 4 ,.thus enabling the necessary movement of the pin 4 when the arts are to whereby the device 0 may be disengaged ot the chain B. In Fig. 4 the pin'has been turned on the axis vof the shank 4:through half a circle, and it has also been turned through an approximately central minor axis of said shank to bring the interned end of the finger 4 against the outer face of the I hook 3, the pin being held in this relation by the spring 7. g

I Having fully described my invention, I claim: l

1. A device of the type set forth, comprisformed as hooks, one of the hooks having a recess, and having its shank formed with a parallel and inclined, a transversely disposed the hooks having a recess,and thepin hav-' on the body part to uncover the hooks, and

shank of the: pin and to cause the ,finger to remain engaged inlthe recess, thereby holding the in in position to close the hooks.

2. A d viceof the type setiorth, comprising a body part-having its ends formed as books, a locking pin which is associated with the body part insuch' manner that its shank may closeboth of thehooks, one of,

ing a finger formed for engagementjnthe," recess, the pin being axially movableto pi ovide for the disen agement or the, finger from the recess and elng pivotally movable a spring for causing the pin to normally remain in posit-ion to close the hooksand with its finger engaged in said recess, 1 I v 3.- A device of the type set forth compris ing a body part ot' S-shaped outline and having reversely. curved hookmembers, a f locking pin passing through said body part "and related thereto to have both axial and pivotal components of movement, an expan sivecoil sprin surrounding said pin atone side of the be y part",- a sleeve ,inclosing said. spring, and a finger provided on the other 7 end of said pin for ehgagemengwith the ads?" j'acent hook 'member' under the tension {of said spring. x

In testimony whereoil have hereunto my hand in presence-of'twosubscribingwiit locking pin, the shank of which passes nesses. s loosely through the opening, the'pin having a finger formed at one end thereof for en Witnesses: w 4 Y gagemenfi with the recess, and a spring ar- GRACE: mm,
